An authorization decision comes from the assessment and the treatment plan, not from the claim. A reviewer reads what you measured, when you measured it, who signed it, and whether the plan names the hours you billed. Answer those questions with dates, instrument names and scores, and the packet reads in one pass.
What this covers
- Maryland Medicaid requires a comprehensive diagnostic evaluation with a caregiver interview, developmental history, direct observation against DSM-5 criteria, and a stated diagnosis before it authorizes ABA.
- West Virginia Medicaid wants the qualifying diagnostic assessment inside 24 months, with the severity level stated, plus an annual physician’s order.
- Florida Medicaid requires the Vineland-3 Comprehensive Parent Interview Form and the BASC-3 PRQ scored and reported, with the scoring report sent with the request.
- TRICARE accepts requests only as units: 97153 per week, and 97155, 97156, 97157 and 97158 per month, with each location named.
- A missing signature is answered with an attestation, not a late signature, and an attestation cannot backdate a plan of care.
The reviewer is not deciding whether the patient needs treatment. The reviewer is deciding whether the record proves the treatment that was billed.assessment documentation is the evidence file for every unit that follows
Assessment documentation has two readers. The clinician writes it with the patient in the room. The reviewer reads it months later, with no patient and one question: does this record support the service and the units on the claim?
What the reviewer opens first
A prior authorization is decided on the assessment, and the reviewer has no context beyond the file. Four things have to be findable without hunting: who completed the assessment, which instruments were used and when, what the scores and the observation show, and how the deficits limit daily functioning.
State manuals list the components. Maryland Medicaid requires a comprehensive diagnostic evaluation before it authorizes ABA, carrying a caregiver interview, the patient’s developmental and psychosocial history, direct observation of behaviors consistent with DSM-5 criteria for autism, current functioning across the major domains of development, and the presenting diagnosis.
Maryland names the professionals who can complete the evaluation: developmental pediatricians, pediatricians, pediatric neurologists, child psychiatrists, clinical psychologists, neuropsychologists and nurse practitioners with ASD diagnostic training. The ABA assessment and plan that follow come from a psychologist, BCBA-D or BCBA.
The assessment also has a shelf life. West Virginia Medicaid requires the qualifying diagnostic assessment within the previous 24 months, with the severity level stated, and Connecticut wants the medical evaluation behind the referral confirmed within 12 months.
The elements payers name in writing
Payers differ on instruments and agree on structure: named tools, dated results, observed behavior in measurable terms, and a statement of how much support the patient needs.
| Payer | What the assessment has to show | Where it is checked |
|---|---|---|
| Maryland Medicaid | Caregiver interview, developmental history, direct observation against DSM-5 criteria, current functioning across domains, stated diagnosis | Prior authorization request |
| TRICARE ACD | Date and time of the updated assessment, assessment tools administered, deficits and excesses that impede functioning, ability to take part in treatment | Treatment plan submission |
| Florida Medicaid | Vineland-3 Comprehensive Parent Interview Form and BASC-3 PRQ for ages 2 through 18, administered, scored and reported | Authorization request, with the scoring report |
| NC Medicaid (RB-BHT) | Adaptive behavior assessment within 3 years (VABS-3, ABAS-3 or DP-4), developmental or cognitive assessment within 1 year under age 8 | Treatment plan and authorization |
| West Virginia Medicaid | Diagnostic assessment within 24 months by a qualified provider, severity level stated, annual physician’s order | Prior authorization request |
Florida Medicaid requires the complete scoring report, including outcome measure scores, with the authorization request. A narrative that calls social communication moderately impaired, with no instrument, score or date, is not evidence.
Outcome measures payers read
Standardized measures turn progress into a number a reviewer can compare. TRICARE names the instruments and intervals: the Vineland-3 and SRS-2 annually, and the PDDBI and PSI-4 or SIPA every six months. Providers are expected to document a direct relationship between a score change and a change in the plan.
A flat score with an unchanged plan reads as a plan nobody reviewed. The same score with a dated protocol change, a medication adjustment or a documented ceiling effect reads as clinical judgment. Florida Medicaid applies the same logic at renewal: core instruments repeat every 12 months while the assessment and behavior plan are updated at least every six months.
- Every six months: PDDBI and PSI-4 or SIPA, TRICARE
- Every 12 months: Vineland-3 and SRS-2, TRICARE, and the core instruments at reassessment, Florida Medicaid
- Within 3 years: adaptive behavior assessment, NC Medicaid
- Within 24 months: diagnostic assessment, West Virginia Medicaid
Adult behavioral health works the same way with different instruments. The MIPS measure Depression Remission at Twelve Months counts remission as a PHQ-9 or PHQ-9M score under 5 at twelve months, plus or minus 60 days from the index event, and only a score inside that four month window counts.
Write the plan so the units hold
The plan authorizes the work you bill. TRICARE accepts a request only as units: 97153 per week, and 97155, 97156, 97157 and 97158 per month. It also names the location of each service and states whether the case runs a sole provider or a tiered delivery model.
NC Medicaid requires the plan to state intensity in hours: direct service, observation and direction, excluding case supervision and caregiver training, with the targeted ratio of 97155 to 97153 and a clinical justification for the hours. Default service hours are not allowed, so intensity follows from the assessment.
Florida Medicaid wants the units requested for each procedure code and the medical necessity for that number, plus a supervision plan naming the authorized supervisors. The plan is also the ceiling: coverage runs to 40 hours a week of intervention as indicated in the prior authorized plan.
| Rule | What it means in the record |
|---|---|
| 15-minute units | Florida Medicaid: divide total minutes by 15. A remainder of 8 minutes or more bills as a unit, and under 8 minutes does not. |
| Daily caps | Maryland Medicaid: 97151 and 97153 cap at 32 units a day. A reassessment is authorized at 12 units. |
| Time-based therapy | Medicare: document start and stop times or total time for 90832, 90834 and 90837, choose the code closest to the actual time (16 to 37, 38 to 52, 53 or more minutes), and do not report under 16 minutes. |
| Supervision | The CASP practice guidelines put two hours of case supervision for every 10 hours of direct treatment at the general standard of care. Maryland requires direction equal to at least 10 percent of direct service hours. |
List every procedure code with its weekly or monthly units, then check the total against the payer’s caps and the assessment.
A goal with no service behind it is padding. A billed service with no goal is the finding an auditor writes up.
Florida Medicaid wants the medical necessity for the units requested. Say why the case needs 20 hours a week rather than 10.
Signatures, dates and amendments
Medicare treats a missing signature as a claim error. Reviewers look for signed and dated documentation from the person responsible for the care. The remedy for a missing signature on anything except an order is an attestation statement from the author of the record, and an attestation cannot backdate a plan of care.
When a contractor asks for an attestation or a signature log, the practice has 20 calendar days from the phone contact or the request letter, and the review period extends by 15 calendar days once it arrives. Those timeframes do not apply to Comprehensive Error Rate Testing reviews.
Under the Medicare Program Integrity Manual, an amendment or delayed entry must identify itself as such, give the date and author, and leave the original content readable. Entries that skip those steps are excluded from review even when the exclusion causes a denial.
State manuals add their own rules. Maryland wants a legible signature with the printed name and title of the person who provided the care, plus the start and end time of the service. Florida requires the assessment and plan signed by the Lead Analyst and the parent or guardian. NC Medicaid requires the plan signed by the responsible provider and the legally responsible person before services start.
The pre-submission review
- Assessment dated inside the payer’s window, with every instrument named, scored and attached
- Direct observation of the target behaviors in measurable terms
- Diagnosis carried to the highest specificity, with the severity level where the payer asks for it
- Goals with a baseline, a measurement method, mastery criteria and a target date
- Units listed by procedure code, with the medical necessity for the number requested
- Supervision plan naming the authorized supervisor and the ratio
- Caregiver training targets and the sessions completed to date
- Signatures from the clinician and the parent or guardian, dated
- Consent to treatment, the referral or order, and any IEP on file
When documentation is the reason for a denial, the remittance names the gap. CARC 197 covers a missing precertification or authorization and 198 one that was exceeded; CARC 250 covers an attachment that was the wrong document. CARC 16 says the claim lacks information and requires a remark code, which is where RARC N206 (supporting documentation does not match the claim) and N237 (incomplete or invalid patient medical record) appear. CARC 15, for a missing or invalid authorization number, was deactivated on May 1, 2018.
A documentation problem also spends the decision clock. Under CMS-0057-F, impacted payers send prior authorization decisions within 72 hours for expedited requests and 7 calendar days for standard requests. A packet returned for a missing scoring report or an unsigned plan burns days you cannot recover before the authorization ends.
Two controls keep a packet whole: a review of the finished file before it uploads, and a monthly read of what came back denied. Comprehensive chart auditing covers the first. Behavioral health revenue cycle management keeps assessment dates, instrument intervals and authorization end dates in one place per patient.
Behavioral health assessment documentation questions
The assessment, the instruments and scores behind it, the observation notes, the diagnosis with its severity, and the treatment plan written from them. Payers also expect the referral or order, the consent to treat, and the signed plan. Every service note then points back to that plan, which ties the billed units to the clinical record.
It depends on the payer and the document. West Virginia Medicaid requires the diagnostic assessment within the previous 24 months. NC Medicaid accepts an adaptive behavior assessment from the last 3 years but wants a developmental or cognitive assessment from the last year for a child under 8. Connecticut wants the medical evaluation inside 12 months.
TRICARE requires the Vineland-3 and SRS-2 annually and the PDDBI and PSI-4 or SIPA every six months. Florida Medicaid requires the Vineland-3 Comprehensive Parent Interview Form and the BASC-3 PRQ, repeated with reassessment every 12 months, with the scoring report sent with the authorization request. Other states name their own instruments.
For Medicare, file a signature attestation from the author of the record. An attestation cannot backdate a plan of care, and it does not apply to orders. Contractors allow 20 calendar days to supply the attestation or a signature log, and the review period extends by 15 calendar days once they receive it.
Yes, and the Medicare Program Integrity Manual sets the method. The amendment must identify itself as an amendment, show its date and author, and keep the original content readable. Reviewers exclude entries that skip those steps, even when the exclusion leads to a denial. A dated addendum is defensible.
The bottom line
Assessment documentation is judged by a reader with no context and a decision clock running. Name the instruments, date the scores, state the severity, and write the plan so the units follow from it. Check the file before it uploads, because the review happens whether or not the packet is ready.
